/**
@class wxListCtrl
A list control presents lists in a number of formats: list view, report view,
icon view and small icon view. In any case, elements are numbered from zero.
For all these modes, the items are stored in the control and must be added to
it using wxListCtrl::InsertItem method.
A special case of report view quite different from the other modes of the list
control is a virtual control in which the items data (including text, images
and attributes) is managed by the main program and is requested by the control
itself only when needed which allows having controls with millions of items
without consuming much memory. To use virtual list control you must use
wxListCtrl::SetItemCount first and override at least wxListCtrl::OnGetItemText
(and optionally wxListCtrl::OnGetItemImage or wxListCtrl::OnGetItemColumnImage and
wxListCtrl::OnGetItemAttr) to return the information about the items when the
control requests it.
Virtual list control can be used as a normal one except that no operations
which can take time proportional to the number of items in the control happen
-- this is required to allow having a practically infinite number of items.
For example, in a multiple selection virtual list control, the selections won't
be sent when many items are selected at once because this could mean iterating
over all the items.
Using many of wxListCtrl features is shown in the
@ref page_samples_listctrl "corresponding sample".
To intercept events from a list control, use the event table macros described
in wxListEvent.
<b>wxMac Note</b>: Starting with wxWidgets 2.8, wxListCtrl uses a native
implementation for report mode, and uses a generic implementation for other
modes. You can use the generic implementation for report mode as well by setting
the @c mac.listctrl.always_use_generic system option (see wxSystemOptions) to 1.
@beginStyleTable
@style{wxLC_LIST}
Multicolumn list view, with optional small icons. Columns are
computed automatically, i.e. you don't set columns as in
@c wxLC_REPORT. In other words, the list wraps, unlike a wxListBox.
@style{wxLC_REPORT}
Single or multicolumn report view, with optional header.
@style{wxLC_VIRTUAL}
The application provides items text on demand. May only be used
with @c wxLC_REPORT.
@style{wxLC_ICON}
Large icon view, with optional labels.
@style{wxLC_SMALL_ICON}
Small icon view, with optional labels.
@style{wxLC_ALIGN_TOP}
Icons align to the top. Win32 default, Win32 only.
@style{wxLC_ALIGN_LEFT}
Icons align to the left.
@style{wxLC_AUTOARRANGE}
Icons arrange themselves. Win32 only.
@style{wxLC_EDIT_LABELS}
Labels are editable: the application will be notified when editing
starts.
@style{wxLC_NO_HEADER}
No header in report mode.
@style{wxLC_SINGLE_SEL}
Single selection (default is multiple).
@style{wxLC_SORT_ASCENDING}
Sort in ascending order. (You must still supply a comparison callback
in wxListCtrl::SortItems.)
@style{wxLC_SORT_DESCENDING}
Sort in descending order. (You must still supply a comparison callback
in wxListCtrl::SortItems.)
@style{wxLC_HRULES}
Draws light horizontal rules between rows in report mode.
@style{wxLC_VRULES}
Draws light vertical rules between columns in report mode.

Changes the order in which the columns are shown.
By default, the columns of a list control appear on the screen in order
of their indices, i.e. the column 0 appears first, the column 1 next
and so on. However by using this function it is possible to arbitrarily
reorder the columns visual order and the user can also rearrange the
columns interactively by dragging them. In this case, the index of the
column is not the same as its order and the functions GetColumnOrder()
and GetColumnIndexFromOrder() should be used to translate between them.
Notice that all the other functions still work with the column indices,
i.e. the visual positioning of the columns on screen doesn't affect the
code setting or getting their values for example.
The @a orders array must have the same number elements as the number of
columns and contain each position exactly once. Its n-th element
contains the index of the column to be shown in n-th position, so for a
control with three columns passing an array with elements 2, 0 and 1
results in the third column being displayed first, the first one next
and the second one last.
Example of using it:
@code
wxListCtrl *list = new wxListCtrl(...);
for ( int i = 0; i < 3; i++ )
list->InsertColumn(i, wxString::Format("Column %d", i));
wxArrayInt order(3);
order[0] = 2;
order[1] = 0;
order[2] = 1;
list->SetColumnsOrder(order);
// now list->GetColumnsOrder() will return order and
// list->GetColumnIndexFromOrder(n) will return order[n] and
// list->GetColumnOrder() will return 1, 2 and 0 for the column 0,
// 1 and 2 respectively
@endcode
Please notice that this function makes sense for report view only and
currently is only implemented in wxMSW port. To avoid explicit tests
